POST SHARPENER, DRIVER, AND FULLER.

SPECIFICATION forming part of Letters Patent No. 776,566, dated December 6, 1904.

Application filed February 10, 1904. $erial No. 192,976. (No model.)

' To (all whm'n, if TIY/PI/Z/ con/(term- Be it known that I, \VILLIAM H. THOMAS, a citizen of the United States, residing at Fulton, in the county of Oallaway and State of Missouri, have invented certain new and useful Improvements in Post Sharpeners, Drivers, and Pullers, of which thefollowing is a specification.

This invention provides in a single organized machine means for sharpening posts, driving the same, and withdrawing unused posts when required for any purpose. A single actuating means operates the different mechanisms for performing the several classes of Work, thereby greatly simplying the machine and reducing the number of working parts to the smallest amount possible, which is a desideratum from a point of lightness and cost of maintaining the machine in working condition.

For a full description of the invention and themerits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and draw ings hereto attached:

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a machine embodying the invention, showing the same when in operation for driving a post, stake, or the like. Fig. 2 is a longitudinal section of the operating mechanism, showing a portion of the sled in transverse section. Fig. 3 is a View similar to Fig. 1, showing the machine as used for extracting a post, stake, or pin. Fig. 4 is a side view of the machine. Fig. 5 is a detail perspective view of the inner end portion of the lever.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The working parts are mounted upon a support of suitable construction for movement over the field or ground, and by preference a sled 1 is provided, as the same gives greater stability and steadiness to the machine when in operation. The sled may be of any substantial construction and is adapted to be propelled over the ground in any determinate way. A platform 2 is mounted upon the sled and is secured thereto by any suitable fastening, as the bolt 3, which passes through a slot 4 of the platform 2, thereby admitting of adjustment of said platform trai'lsversely of the sled, which is of advantage to admit of bringing the hammer in position to strike the post without necessitating shifting of the sled or movement thereof to bring the working parts in the required position. Standards 5 and 6 project-u nvard from the platform 2 and are connected by longitudinal bars 7 and braced by stays 8. The standards comprise companion bars which are spaced apart a distance to receive between them the lever 9, provided at its outer end with a weigl'it 10, which may constitute a hammer or driver 10.

The lever 9 is fulcrumed intermediate of its ends to the longitudinal bars 7, as indicated at 11, and its inner or rear end comprises spaced portions which extend upon opposite sides of the tappet-wheel 12, provided with oppositely-disposed tappets 13 for actuating the lever when the machine is in operation. The spaced portions at the inner or rear end of the lever 9 may be provided in any determinate way and preferably consist of plates bolted or otherwise secured to opposite ends of the lever and having portions extended to project upon opposite sides of the tappetwheels. The hammer 10, applied to the outer end of the lever 9, may be of any construction and design.

The tappetwheel may be operated by any power, and inasmuch as the machine is designed for manual power a pinion 14 is provided and is in mesh with the teeth of the tappet-wheel 12, and its shaft is provided with a crank 15, to which the hand-power is applied. Upon rotating the tappet-wheel 12 in the direction indicated by the arrows in the drawings the inner or rear end of the lever 9 is depressed and the hammer elevated, and the instant the tappets clear the lever the hammer falls and delivers a blow upon the Aspiring post, stake, or the like to be'driven.

or buffer 16 is provided to receive the blow of the hammer when the post, stake, or the like has been driven beyond-the range of the hammer when at its lowest point, thereby obviating injury to the machine.

The cutter for pointing, trimming, or otherwise preparing the posts preliminary to d riving consists of a blade 17, attached to the pivoted beam 18, which is connected by link 19 to the outer end of the lever 9, so as to move therewith. The blade 17 may be of any design best calculated for the work in hand and is arranged with reference to the support or sled to enable convenient and effective operation in the cutting or trimming process. By having the beam 18 connected to the hammer the weight of the latter is utilized for forcing the blade 17 through the material, thereby greatly facilitating the work and enabling comparatively large portions of the material to be removed from the timber when pointing the posts or otherwise cutting the same.

The post puller or extractor comprises standard 20 and rope or cable 21. The standard 20 is located at one side of the support or sled. One end of the rope or cable is attached to the beam 18 and the other end is adapted to be connected to the post 23 or like part to be removed from the ground. hen the rope or cable 21 is connected to the parts 18 and 23 substantially as indicated in Fig. 3, descent of the hammer efi'ects an upward pull on the post, stake, or the like, as will be readily comprehended. The construction admits of the weight and force of the descending hammer being utilized for driving the post, for operating the cutting mechanism, and for working the post-extracting means, as will be readily comprehended. \Vhen the sled is moved into position either for driving or extracting a post and the parts do not come into desired position, transverse adjustment of the platform 2 may be effected by loosening the fastening 3 and shifting the platform 2 upon the sled, after which a retightening of the fastening 3 secures the parts, thereby obviating the necessity of shifting the sled or propelling the same either backward or forward in order to properly position the machine with reference to the work.

The beam 18 is adapted to be pivotally connected at one end to the sled, as indicated in Fig. 1, or at a point between its ends to the standard 20, as indicated in Figs. 3 and 4, according to the special work to be performed. When the beam is pivoted as shown in Fig. 1, the cutter 17 may be used for trimming posts or stakes, and when the beam is pivoted to the standard 20 the post, pin, or the like to be extracted is connected by rope or cable 21 to the end previously pivoted to the sled, so that downward movement of the end of the beam connected to the hammer causes the opposite end to ascend and pull upward upon the part to be extracted.

Having thus described the invention, what is claimed as new is- 1. In a machine of the character described, the combination of a supporting-framework, a lever pivoted thereto intermediate of its ends and provided at one end with a weight and at its opposite end with spaced portions, and a tappet-wheel adapted to operate between said spaced portions and provided with oppositely-extended tappets, substantially as specified.

2. In a machine of the character described, the combination of standards, each composed of spaced members, spaced longitudinal bars connecting corresponding members of the standards, a lever arranged to operate in the space formed between the longitudinal bars and the members of the standards and provided with a weight, and atappet-wheel journaled between said longitudinal bars and provided with tappets for operating said lever, substantially as set forth.

3. In a machine of the character described, the combination of a lever having a weight at one end, means for oscillating said lever, a
